Tendencies and Perspectives of the Emotions Usage in Robotics

Abstract

Emotions are psychological phenomena present in the living beings. However, there is still no consensus for a more precise definition of the emotions. As a complex concept, the emotions can be part of a robot model for different usage in variety of robots. This paper presents the state of the art of robot behavior models that use emotions in a chronological order. The aim of this paper is to formalize the usage of emotion in robotics. Thus, a definition and explanation of a set of distinct parts in robotic models influenced by emotions is proposed. On the other hand, the properties of robots that use emotions, the so-called emotional robots, are also explored. As a result, the most important different properties that emotional robots should possess are retrieved and explained in detail. The aim of the formalism presented in this paper is to give tribute to the work already done and to give possible directions for the future work with emotional robots.
